This invention' relates to improvements in `garage doors or the like. y Y It is 'well-known that large doors such as used for garages or 4the like, arequite heavy,

dificnlt tohandle, and do not `properly insu.`

late the chamber withI which they areused,

and one of the objects of the' present' invention is to provide a door structure which `will eliminate such 'disadvantages' Another object. of the invention furL nish a garage door `formed mainly'of light sheetsy of tex` i I 2 A still further object is to provide acompo'site door fstructure which may be readily assembled, and the parts'of Vwhichwill re-L yWith the foregoing objects outlined and with other objects in view whichV will appear 1 as the description proceeds, the invention con# sists inf'the novel featuresl hereinafter de` scribed' in detail, illustra-ted` in the' accom# panying drawings, and i more particularly;l

pointedout in the appended claims.l 'Referring to the drawings,"

' Fig. 1 is an'elevatlonof a portion "ofaf garage door made in accordance with my invention, and viewed from, the inner side thereof.

Fig. 2 is an enlarged parts of the door. Figs. 4 and 5 are sectional-views'taken respectively on lines 4 4 and 5 5 of Fig'. 1.

Fig. 6 is a'persp'ective view, partlyin section, of a detail. l'

InV the drawings, the 'door illustratedis formedof'superposed sections 7, 8 and 9, thatv are pivotally vconnected together along hori" zontal lines by means of hinges 10.4 Sectiony 7 may be of any suitable construction, provided with windows 11,but the sections 8 and 9'` insulating material su'ch asl cello' y vertical sectional view'V of a detail, taken on the line 2"2 of -Ffig.-` 1;

Fig. 3"is a sectional view of a. detail, and',V illustrating the -manner of assembling theV panel 17 havinga thin metalsheetfacing 18.l This metal facing is` onV the outside of the door or that side which is` exposed to the weatherwand.A beside' .serving as aI protection against the elements, Alends a strength tothe door aswell as preventing ready cutting. f

through-the cellotex panel by an intruder.'`

4 To the yinner `face of thepanel 17 at" tach'ed, preferably by `an adhesive', top and `bottom battens 19 and 20 respectively, side battens `21, and centerbattens '22,: all of these being providedl with grooves 23, in their faces which contactwith the inner face of the panel 17.A Thesegrooves are located` near-'fthemarginal edges farthest reinovedV from theirouter `edges to receive any excess of glue or adhesivev which might be squeezed oi'itfro'm the joints,

thereby preventing flowingof .the adhesive` onto theinner face of the panel to soil the same.

On the outside'of each door section, wherever a'center" hatten' 22 occurs, is provided l a muntin 2,4, the same being seated within av I groove 25 provided fin the outer face' of the panel 17, the muntinand panel preferablyy not beings'ecured to each other. The metal sheets 18 abut the sides of the muntin 24 and are; overlapped on the outside. :by lateraleX- tensions 26formed on the muntins at each side thereof.

, lThefedges ofthe top .andbottom ra-ilsl/lf andl and of theysidestiles which receive the` panel 17, are specially formed to providea f compound curved or ogee surface shoulderv 28,` beveled surface 29, shoulder 30, plain surface 31, inclinedor wedge surface 32, and

p face Theshoulder 28; and surface 29v mireille make up a wedge"shapedv groove', shoulder 30, the surfaces 31 and 32 make up; another vWedge-shaped groove. The upper 'and lower endsof the side `stiles ,are shaped to conformrto that of the especially formed edgesof the top and bottom rails by having afcompound curved or ogee surface37, face 38, beveled edge 39, face 40, edge 41,inclined or wedge face 42, and facek 43. The parts 37 to 43 inclusive vengage withthe 27 to 33 inclusive, respectively', when the rails and stiles are assembled vinto vaframe, and the` joint between them is reinforced by dowels 45 throughout.y

The upper and lower ends of the muntins are also specially formed tol provid-e compound curved or 'ogee surfaces 57 which conform to and abut the surfaces 27 of the top i auf and bottom rails. The side edges of the muntin-extensions 26 may also be of ogee formation, but this forms no part of the invention, and is not illust-rated. They are also provided with projections, the'faces 58 and 59 of'which engage with the facesl28 and 29 of the top and bottom rails. The

faces 27 and 28 of the rails 14, and 15 andl stiles 16 areat an acute angle to each other and form a rib that is' `received between the faces 57 and 58 which form notches in the ends ofv the muntins. Thus itwill be seen thatfthe muntins, not being attached to the panels 17, but being loosely located fin the groove of the panels are prevented by the Wall of said groove from lateral andl rear-y center battenvs have their upper and lowery ends-shaped to conformto the contour of the,

top and bottom battens in order toproduce the miter effect, 65, though this effect maybe produced otherwise. With the battens applied. the panel and battens are subjected to the action of an edging tool, which uniformly produc-es the surfaces 49, 50, 51 and 52 and the parts are then ready for assembling.

` Assembling is accomplished in a standard ldoor press which is notillustrated, the parts i being laid'upon the press bed or table 66 as is illustrated in Fig. 8 with the metal sheets 18lose vupon the top o f the panel 17, and the panel .17 with 'its attached battens 19 and 21 resting upon vthe table 66. The press is then put `into 1operation moving the top and bottom rails 14 and 15 against the ends rofthe side stiles 16 and the stiles 16 toward each other, diring' which movement they `wedge surface 2 ride up the wedge surfaces 32 causing the entire panel 17 with itsmetal facing 18- and attached battens. to lift from the table 66. This-liftin'g'action continues until the parts are entirely together, at which time thesheet metal facing 18 will be securely bound against the. shoulders `28 of the rails 14 and 15 and stiles 16. In cases where the sheet metalv facing 18 is not employed, the; panel 17 ritself engages the shoulders28 tightly -to produce a substantially watertight joint. It will be observed that lthe beveled surfaces clamping action upon the pane-l unit is between the shoulders 28 and the wedge surfaces 32 of the rails and stiles,l and that because of the yielding nature of the material composing the panel 17, the joints between the rails 14 and 15 and stiles 16 will always be permitted to close, since if the ypanel comes into Contact with the shoulders 28 fbefore the said joints are closed, the compressibility of the panels 17 will permit further -movementI until the rails and stiles meet in proper oining fit.

'It will befobserved that in assembling, the

metal sheets 18 arel merely laid upon the panel 17 and since these sheets have more or less buckle portions f thereof especiallywat their edges will extend away from the panel.v

This makes it necessary thatthe -panel v17 and metal facing 18, during assembling, shallA be kmoved against lthe shoulder 28 with a `movement more or less perpendicular there-- to, while the rails 14 and 15 and stilesl are being closed against 'the edges of the panel Any attemptto assemble the panel parts. with vits sheet metal facing by moving it directly .into the rail and 4stile groove wltha soy ,sa j

direct edgeways movement Awould result in thesheet metal striking the'edge of the ogee surface 27,' and even' without the sheet metal facing being present,- this would alsov occur, with the panel 17 which also has more or'less.

buckle. ,v

. Having thusdescribed my invention, what I claim as new and desire to secure by Letters Patent is: v

1. In panel construction, the combination of a sectional grooved frame and a panelmember inclosed'thereby, one wall ofthe frame groove being beveled, andthe-.panel member being engaged onlywith said beveled Wall when the parts arejuxtaposed priorfto assembly, said beveled wall servingto move one face ofthe panel member against van op-l posite wall of the frame groove when they frame sections are'moved toward the panel member during assembling, the panel member including a compressible felted fibre portion which permits the frame joints to close even after the panel member hasengaged the said opposite groove wall.

v2. Ina door construction, the combination of a sectional groovedframe having a surface at anv acute angle to one wall ofsaid groove forming arib, a muntin having its ends'notched to receive said rib, a panel member having one of its faces engagedwith said rib, the oppositeface of the panel member having beveledengagement withfthe otherwall of said framev groove. .Y

3. In a door construction, the combination of a sectional grooved frame having al surface at an acute angle to one wallof said grooveforming. a rib, a muntin havingl its end notched to receive saidA r1b, apanel member having one of its faces engaged with said,A

rib, the oppositeface of the panel member having beveled engagement with the other Wall of said frame groove, the panel member y of a sectional grooved frame having a surengaged said rib.

face at an acute angle to one wall of said groove forming a rib, a muntin having its end notched to receive said rib7 a panel member having one of its faces engaged with said rib, the opposite face of the panel member having beveled engagement with the other wall of said frame groove, the panel being of a compressible nature-to permit the frame joints to close during assembling even after the panel has engaged said rib.

5. In a door construction, the combination of a sectional grooved frame having a surface at an acute angle to one wall of said groove vforming a rib, a muntin having its end notched to receive said rib, a panel member having one of its faces engaged with said rib, the opposite face of the panel member having beveled engagement with the other wall of said frame groove, the panel member being grooved and receiving the muntin in said groove, the panel being of a compressible nature to permit the vframe joints to close during assembling even after the panelhas 6. A door comprising a sheetl of fibrous in sulating material, top, bottom and end battens secured to the edge portions of said sheet and having wedge shaped projections, center battens secured to one side of the sheet, a muntin on the opposite side of the sheet, the

center battens having their ends engaging` the top and the bottom battens, cross rails and side stiles having wedge shaped grooves into which the wedge shaped projections eX- tend, other grooves in the cross rails and side stiles into which the edge portions of the sheet extend, the ends of the muntin also eX- tending' into the last mentioned grooves.

`7. In panel construction, the combination" of a. sectional grooved frame Aand a panel member enclosed thereby, onej wall of the frame-groove being beveled and opposing two o'set walls of the groove which (latter offset walls are substantiallyrparallel with the plane of the frame, the panel member comprising two united layers one of which is of relatively highv compressibility and of greater thickness than the distance between the two said offset walls and the other 'of which is of relative negli ible ycompressibility and having a beveled ace, said beveled face being engaged `only with said beveled wallof the groove when the parts are juxtaposed prior to assembly and said beveled face and beveled wall serving to move'one face of the relatively highly compressible layer :aga-instithe outer of said offset walls ofthe groove when the. frame sections are moved toward the panel member during assembling, the relativelyhighlyi compressible layer be` ing compressed to permit the frame joints to close even after the said relatively highly compressible member hasl engaged the said outer oset wall of the groove.y

8. In panel construction, the combination of a sectional grooved frame, a` compressible l `panel of substantially uniform thickness,

battens' of relatively non-compressible materialsurrounding and secured to the panel4 and having an outer beveled face, the combined thickness yof the panel and batten at the extreme outer 'edgeof' the panel being less than the distance between opposite .walls of the frame groovey and the thickness of,A

said parts-increasing toward the centervpor- Y tion of thevpa-nel to a degree that when the' f joints of the outer frame are entirely closed the compressible panel will be compressed at its edges betweenthe battens and one wall of the frame groove and the battens will be engaged with one wall of the groove. i l

9. In panel construction, the combination of a sectional grooved frame, one of two opposite walls of the groove being beveled, a. compressible felted fibre sheet and ametal sheet forming a panel, wooden battens surf rounding Aand secured to the panel and hav-H ing an outer beveled e face, the combined y thickness of the metal plate, fibre sheetand batten at the eXtreme outer edge of the panel` being less than the distance between the Abeveled and opposite walls of the frame groove and the thickness of said partsuin- Vcreasing toward the central portion ofthe panel to a degree that when the joints of the' outer frame are entirely closed the compressible sheet will be compressed at its edges between the batten which then engages the beveled wall of the frame groove and they metal sheet which engages the opposite wall of the frame groove.
